Cell Growth The Cell Cycle is the series of events that cells go through as they G1 phase grow and divide. During the Cell Cycle, a cell grows, prepares for division, and divides to form two daughter cells, each of which begins the cycle again. Cell

S phase replication DNA the period of growth that occurs between cell Interphase dividison

G2 phase Interphase is divided into three phases: G1, S, & G2

G1 Phase S Phase G2 Phase

The G1 phase is a period of The S phase replicates During the G2 phase, many of activity in which cells do most and synthesizes the organelles and molecules of their growing. Cells will DNA molecules. When DNA required for are increase in size and synthesize replication is completed, the cell produced. When G2 is new and organelles. enters the G2 phase. completed, the cell is ready to enter the cell is ready to enter the M phase.

Interphase Interphase is divided into Prophase - Chromatin three phases: G1, condenses into S, & G2 chromosomes Interphase is the in - Centrioles seperate between stages of cell - A spindle forms division. - The nuclear envelope breaks down

Metaphase - The chromosomes Anaphase - The sister line up across the chromatids separate center of the cell into individual - Each chromosome chromosomes and is connected to a are moved apart. spindle fiber at its .

Telophase - The chromosomes Cytokinesis - The gather at oppostie pinches in half. ends of the cell & - Each daughter cell lose their distinct has an identical set shapes. of duplicate - Two new nuclear chromosomes. envelopes will form.
